Chapter 11: Menu Capacity Analysis

In this chapter:


The process of menu analysis requires an understanding of menu type, structure, planning and content. It is not all about number crunching; both qualitative and quantitative aspects of menus are equally important.

The methodology outlined in this chapter can be used to evaluate the range and capacity of menus used in a healthcare setting. A menu capacity analysis provides evidence of compliance with applicable hospital food standards. Each home country’s standards vary slightly, so it is important to check the ones that apply to your organisation. It is also recommended that a new analysis is carried out for each substantial menu change.

In addition to the standard menus, it is recommended that special and therapeutic menus (i.e., texture modified menus, paediatric menus, finger food and allergy menus) are also analysed using the same methodology to ensure energy and protein needs are met across the spectrum of menus.

It should be noted that the aim of the menu capacity analysis is to outline the hypothetical capacity of the menu and is based on patients eating 100% of their meals. Patients who are nutritionally vulnerable may consume less of their meals due to nutrition impact symptoms like swallowing difficulties, poor appetite and fatigue. Therefore, menu planners should be cautious of menu analysis figures when aiming to show compliance with any standards. Other factors that will impact a patient’s intake still need to be considered, such as taste, appearance and portion size.

Methodology for analysing menu capacity  

The structure of a menu capacity analysis is based on the day parts model outlined in Chapter 10, Table 10.4. Each day has both a ‘fixed’ and a ‘variable’ component.

Fixed amounts are used to estimate the daily intake of energy and protein from breakfast, snacks and drinks. As there are multiple products available to patients at breakfast and snack/drink rounds - using the average of these products provides a more measured approach to analysing the capacity of a menu.

Variable amounts are used to reflect the range of energy and protein available from the different meal choices on the menu for the lunch and dinner meal services.

This chapter illustrates two worked examples of a menu capacity analysis based on a cyclical and à la carte standard menus. Both examples illustrate how the minimum/maximum method of menu analysis is used to show how the menus meet the needs of both nutritionally well and nutritionally vulnerable patients.

Tables 11.2, 11.3, 11.4, 11.5 and 11.6 depict a worked example of a menu capacity analysis of a sample day from a 2-week cycle menu.

Tables 11.7, 11.8, 11.9 and 11.10 depict a worked example of a menu capacity analysis of a sample à la carte menu.

Table 11.1: Outline of minimum/maximum methodology

 

Cyclical menu

A la carte menu

Step 1: Nutritional breakdown

Obtain the energy (kcal) and protein (g) information for all food and drink items on the menu.

Table 11.2

Table 11.7

Notes: Data can be sourced from the food supplier, manufacturer, food labels, calculated in-house using recipe analysis software based on food composition tables, or through a combination of these.

Step 2: Calculate fixed values

Minimum

Table 11.3

Table 11.8

Calculate the minimum ‘fixed’ energy and protein values for breakfast, snacks and drinks

 

Breakfast - calculate the average energy and protein of the breakfast items on offer, as outlined in the standard nutritionally well breakfast in Table 10.4

Snacks - use the total energy and protein for the two snacks with the lowest amount of energy

Drinks - use the energy and protein of 400ml of your lowest energy milk  

Maximum

Table 11.4

Table 11.9

Calculate the maximum ‘fixed’ energy and protein values for breakfast, snacks and drinks

 

Breakfast - calculate the average energy and protein of the breakfast items on offer, as outlined in the standard nutritionally vulnerable breakfast in Table 10.4

Snacks - use the total energy and protein for the two snacks with the highest amount of energy

Drinks – use the energy and protein of 400ml of your highest energy milk  

Notes: For the worked examples in this chapter, the appropriate energy and protein values were taken from Table 10.3. In practice use actual breakfast and snack items figures. Two different types of snacks should be used.

Step 3: Calculate variable values

Minimum

Table 11.3

Table 11.8

Calculate the minimum ‘variable’ energy and protein values for lunch and dinner 

Select a random day in the week and pick the appropriate minimum choice (i.e., that which provides the lowest energy value) at lunch and dinner for the starter (if applicable), main meal and dessert.

Select the 3 minimum choices on the menu (i.e., those which provide the lowest energy value) for the starter (if applicable), main meal and dessert.

Add the total energy together for the 3 lowest options in each course and divide by 3 to get an average for that meal course.

Repeat this for protein.

Maximum

Table 11.4

Table 11.9

Calculate the maximum ‘variable’ energy and protein values for lunch and dinner 

For the same day, pick the appropriate maximum choice (i.e., that which provides the highest energy value) at lunch and dinner for the starter (if applicable), main meal and dessert

Select the 3 maximum choices on the menu (i.e., those which provide the highest energy value) for the starter (if applicable), main meal and dessert.

Add the total energy together for the 3 highest options in each course and divide by 3 to get an average for that meal course.

Repeat this for protein.

Notes: Pick realistic options when choosing carbohydrate and vegetable sides to make up a main course - even if that choice is not always the lowest/highest in energy for that meal service, e.g. when completing a minimum capacity analysis, pick rice to go with chilli con carne, even though mashed potato may be on the menu and provide less calories, similarly you may pick chips to pair with battered fish when completing a maximum capacity analysis, even though rice may have more calories.

Step 4: Calculate average total daily energy and protein

Minimum

Table 11.3

Table 11.8

Calculate the total minimum energy and protein provided over the day

Add together the values for energy and protein for both the minimum fixed and variable components of the day to calculate the totals for each. 

 

 

If the same variable options are available and lunch and dinner, multiply the calculated average minimum values for energy and protein by 2 to represent both main meals (or simply add together lunch and dinner if different options are available). Then add these amounts to the minimum fixed values to calculate the totals for both energy and protein.

Notes: Show the percentage of the nutritional targets met for both the minimum fixed and variable figures as demonstrated in Table 10.1

Maximum

Table 11.4

Table 11.9

Calculate the total maximum energy and protein provided over the day

Add all the values for energy and protein together for both the maximum fixed and variable components of the day to calculate the totals for each. 

 

 

If the same variable options are available and lunch and dinner, multiply the calculated average maximum values for energy and protein by 2 to represent both main meals (or simply add together lunch and dinner if different options are available). Then add these amounts to the maximum fixed values to calculate the totals for both energy and protein.

Notes: Show the percentage of the nutritional targets met for both the maximum fixed and variable figures as demonstrated in Table 10.1

Step 5: Calculate average energy and protein for a cycle

Minimum

Table 11.5

 

Calculate the average minimum energy and protein provided across the three days or three meals

Repeat steps 3 and 4 for three random days in total within the week, including one weekend day.

Add the total energy together for all 3 days from the minimum menu capacity analysis and divide by 3 to get the average energy provided by the minimum choices.

Repeat this for protein.

N/A

Maximum

Table 11.5

 

Calculate the average maximum energy and protein provided across the three days or three meals

Repeat steps 3 and 4 for three random days in total within the week, including one weekend day.

Add the total energy together for all 3 days from the maximum menu capacity analysis and divide by 3 to get the average energy provided by the maximum choices.

Repeat this for protein.

N/A

Notes: Including a Saturday or Sunday ensures consistency of meeting nutritional capacity over the entire week.

Step 6: Compare to nutritional Targets

Minimum

Table 11.6

Table 11.10

Compare the average energy and protein to the nutritional targets for nutritionally well patients.

The average energy and protein from your minimum menu capacity analysis should be equal to or above the targets for nutritionally well patients.

Maximum

Table 11.6

Table 11.10

Compare the average energy and protein to the nutritional targets for nutritionally vulnerable patients.

The average energy and protein from your maximum menu capacity analysis should be equal to or above the targets for nutritionally vulnerable patients.

 

A note on hybrid menus

If a menu contains a combination of both a la carte options (i.e. options that are available everyday) and a cyclical menu (i.e. daily specials), then the two different components of the menu should be analysed separately.

For example, if the menu has the same sandwiches and cold desserts available every day with a rotating menu of daily hot options, the sandwiches and cold desserts should be analysed using the a la carte menu method and the hot options analysed using the cyclical menu method.

Worked examples

The following worked examples of lunch and dinner menus show how the menu capacity analysis methodology can be applied to both cyclical and à la carte menus.

Some nutritional analysis packages allow selection of meal choices from specific days to carry out a menu capacity analysis. In the absence of an appropriate electronic analysis tool, calculations can be carried out manually using an Excel spreadsheet and the energy and protein information from recipe analysis.

Utilising nutritional analysis software

A way to show that a whole menu has capacity to meet the needs of patients, rather than parts of a menu (as shown in the above methodology), is to utilise nutrition analysis software where uptake figures are entered for each menu item (either known or average).

This method shows the capacity of the menu when related to actual (or estimated) patient uptakes. Uptake figures can be entered in percentages, assuming 100% is the whole patient population (e.g. of the main meal options, 65% of patients chose Shepherd’s Pie, 25% had Chicken Pasta and 10% opted for Vegetarian Sausages). 

An advantage of this method of analysing capacity is that it includes the actual choices that patients make. The main disadvantage of this methodology is that, if it is based on actual choices, patients may not choose the combination of meals or meal components that reflect how their nutrition targets can be met.

However, users can set uptake figures to show higher energy or healthier choices to show compliance where necessary – like in the methodology outlined in this chapter where specific choices were made to show compliance for those nutritionally well and nutritionally vulnerable.
